To all whom t may concern:

Be it known that l, JoH'N F. GAIL, a citizen of the United' States, residingk at Evanston, in the county o'f Cook and State of ll- 5 linois, have invented certain" neW'an'd useful improvements in" Corner Fastenings, of Which the following is the specification.

My' invention'has reference more particuL larly to a lock vor fastening device which is 10 adapted' to` be'V used in furniture construction, for detachably connecting' the end of a frame member Vtotlie'side of a post, as for example, in;` bed construction, wherein an angle iron side rail of the bed is connected to the.v postet the bed end.

The principal objects of my invention are, to provide improved means for' detachably securing the end of a` longitudinal member of angular cross section,` such as an angle iron, in a socket;` to enablesuch a member to be convenienti",7 secured in the socketin reversed positions; to enable such reversed connection to-be made Without removing or reversing the locking means; toy provide a 25 locking'r device having a toggle action or relatively swinging parts for effecting lthe` clamping' engagement of the longitudinal memberin the'socket; to'provide a. device ofthis character wherein the locking" parts longitudinal member is released; and= in general to-provide-impr'o'ved locking means which is simple and inexpensive, and whichI may be conveniently operated to securely clamp' the endof van vangggle iron* or similar member in a socket.l

On' the draWings,-Fig. 1- is a side view of a fragmentary portion of a post and 'angle iron connected therewith, in accordance with my invention;

Fig. 2,-an enlarged view onthe line 2-2 of Figzll, with the angl'eiron shovvn intransverse section; Y

As shown: oir the drawings, the' reference numeral l indicates' al fragmentary portion of a post,.suolras-the post of a-bed end, and 9, a fragmentary portion of an angle iron, suoli as theV angle iron side railoff' abed",

remain assembled `in the' socket When-` the which is detachably connected'to the post 1f. For the purpose of afiording s'ucliconection the post l is provided with a bracl'et or socket member 3-ony the side thereof, which may be of any suitable form or construction and secured to the'` postiii any desired manner. This socket in the constructionl shown'comprises aplate bent in!i'livertedV U- shape, with the edges of th'e'tivo'legs'T se cured" against the side o'f' the post, and-the connecting Wall Al, between tlieupperends of the'leg's formed so as to` provide sq'uafrel corners adapted to have "the cornerim ofan angle iron fitted' therein. upper wall 4 is a cross plate which has depending ears 6 secured' to the sidewalls or legs 7 of the bracket, to 'provideal sub# stantially rectangular housing` or socket 8' at the upper end'of the bracket;k Thissocket isv adapted'to have the end-of 'the' angle iron 2 inserted therein in thefposition' shown' in full lines yin Fig. Q, or in tliefievers'e p'os'itiony as shown by the dotted lines at 9 in Fig. 2;

For locking theend' of theangleiron' in the socket 8, in either of tfhese'positi'ons, have provided a lockingmemberor device comprising a! pair of expansible eleinent's 10, operated by' a Wing nut 1.1, threaded en a bolt 12,' said bolt being.insertedu transversely through' theI lateral Walls" ofthe" socket 8,- substantially mid- Way Vbetween tlietop and bottom Walls 4- and 5, respectively, thereof', as shown in Fig; Q; The head y13 of this bolt engages against the outer side'.V of' one of the Walls 7' and the Wing nut ll is threaded on the oppositeendofftlie'boltf at the'outer side of the socketI Wall', With-the sleeve '14, loosely telescoped on the stem of the bolt lf2, aud interposed between the Wing nut' 11 and the locking elements 10, to apply pressure from the Wing nut tosaid elements.

VThe Wall of the socketl S'Y adjacent: the' Wi'ng' movement or toggle actioir of the part'slO* thereof, along the line of juncture4 1.6, vvhen pressure is applied theiving nut: lll and: sleeve 14 to the'ibacksoftlietivofelements 1l); The outer' en`d`s-o`fthe' elementsl'are vroun'd- Cil ed at A1 7 to afford in effect a roller or enlarged end for clamping engagement with the angle iron 2. The two parts 10 are correspondingly notched at each end, as indicated at 18, adjacent the juncture line 16 and the clip 19, laid against the backs thereof, and provided with iiiturned ears 20, which engage in the notches 18 and are hooked on their inner ends against the inner faces of the elements 10, so as to hold the two parts 10 together as a unit, while permitting the necessary relative movement thereof, for locking the angle iron in the socket. This clip 19 is preferably bent inwardly along the top and bottom edges, as at 21, to apply a spring pressure against the backs of the elements 10, to hold them normally in retracted position.

As hereinbefore stated, the angle Viron 2 may be inserted in the socket 8 in either of the positions shown by the full lines and dotted lines in Fig. 2, and the opening22,

which is formed, one-half in each of the liarts 10, and also the corresponding opening in the clip 19, is vertically elongated, as clearly shown in Figs. 3 and 4, to permit the necessary shifting of the locking parts 10,-to accommodate either placement of tli-e angle iron 2 in the socket 8.

When the angle iron is inserted in position, and pressure applied to the elements 10, by turning the wing nut-,11. the two elements 10 are forced against the vertical liange of the angle iron, and when engaged ihereagainst, further tension on the elements 1i) by the wing nut 11 effects a toggle actionV or relative swinging movement of the elements 10, along the linel, and this action spreads the outer ends of the respective elements 1() apart, so that in addition to direct pressure of the locking elements 10 in theV direction of the length of the bolt 12, there is also a pressure upwardly by the upper element 10, and downwardly by the lowei` element 10, which forces the vertical flange of the angle iron into close frictional engagement with a side wall of the socket 8, and the horizontal flange of the angle iron againsttlie upper or lower wall as the case may be, of the socket 8. Qbviously, the

elongated openings22 and 23 of the locking elements 10 and the plate 19 permit the locking device to automatically adjust itself between the upper and lower surfaces engaged thereby. When pressure is released from the locking members 10, the spring fanges 21 of the clip 19 return the members 10 to the contracted relative position, so that the angle iron 2 may be readily withdrawn or inserted.

To obviate the necessity of removing the holt 12 when inserting the nail. the upright flange 24 of the angle iron is preferably slotted, as indicated at 23, in Fig. 1. Both ends of the rail or angle iron are slotted in Yof a post having a socket extending latere ally therefrom, a member of angular cioss section having an end adapted to be inserted in said socket, and means for detachably clamping the end of the `member in the socket, said means comprising an actuator and a pair of'clamping members on opposite sides respectively of the actuator and operable thereby to swing relatively and thereby clamp the end of said member inV the socket.
